2 Claims.

The present invention relates to certain new and useful improvements intoothbrushes of the so-called fountain type wherein a hollow handle orthe like serves as a container for a tube of tooth paste and manuallyoperable means is provided to progressively compress and squeeze thepaste from the tube and to deliver it to the customary bristles forready and convenient use, it being the principal obiect of the inventionto structura ly, functional y and otherw se improve upon similarlyconstructed brushes with which we are familiar.

As the opening statement of the in ention implies, we are aware that theart to which the invention relates is made up of var ed tvpes offountain and dispens ng brushes. Therefore, in carrying out theprinciples of the present invention, we seek to add a furthercontribution to the art in the form of a dis ensing brush which,

we believe, is more a tly suited to accomplish results desired by bothmanufacturers and users.

In carrying out our invention, we provide a simple and practical brushwhich is constructed of a pair of complemental sections, said sectionsserving to define a hollow container, providing both head and handle,and serving to effectively house nozzle means in the head, a readilyinsertible and movable tooth paste tube, and a sl dahly mounted followerwhich, when properly operated, serves to effectively and progressivelycompress and express the paste for delivery to the bristles.

Other objects and advantages will become more readi y apparent from thefollowing description and the accompanying illustrative drawings.

In the accompanying drawings, wherein like numerals are employed todesignate like parts throughout the views:

Figure l is a side elevational view of a dispensing or fountain-typetoothbrush constructed in accordance with the principles of the presentinvention.

Figure 2 is a view like Figure 1 but showing the cover sections swung toopen position.

Figure 3 is a top plan view of the brush shown in Figure 1.

Figure 4 is a bottom plan view of the same.

Figures 5, 6 and '7 are enlarged fragmentary sectional and elevationalviews serving to more effectively illustrate the details ofconstruction,

Figures 5 and 7 being on the lines 5-5 and 1-1 of Figure 3.

Figure 8 is a cross section on the line 8-8 of Figure 1, looking in thedirection of the arrows.

Referring now to the drawings by distinguishing reference numerals itwill be seen that the body portion is of sectional construction toprovide a hollow two-part casing Iii. Said casing includes a bottom orreceptacle section H and a complemental cover section E2. The outer endsof said section are fashioned as at It and I4 to provide a head for thecustomary bristles l5. The outer end of the head portion i3 is providedwith a pair of spaced lugs Hi to accommodate an intervening lug ll, saidlugs being pivotally connected together as at 8. Thus the two sectionsare suitably hinged to one another. The inner end of the cover sectionis provided with a spring clip l9 which is releasably engageable withthe detent 20 on the receptacle section whereby to appropriately connectthe two sections together in handle forming relationship. The numeral 2!denotes an eye which may be employed to suspend the brush, when not inuse, from a suitable wall supporting hook or the like (not shown).

The receptacle section I l is provided with diametrical y opposteelongated accommodation and guide slots 22 to accommodate extending endportions 23 on a slide shaft 24 constituting a part of the hand operatedejector 25. The ejector is of the usual follower-type and embodies aplate which is shaped and angled to press against the compressible toothpaste tube 26 in a manner to compress and express the paste therefrom.To facilitate operation, the end portions of the shaft are provided withfinger grips or knobs 21.

The usual screw threaded discharge neck 28 on the tube is threaded intoa screw threaded socket 29 carried by the inner end of a paste deliveryand feeder tube 30. The latter is mounted in the body and head portionsof the casing as shown and has a lateral discharge terminal 3! (seeFigure '7) which is lodged in an aperture provided in the head portion.An opening in the head portion I3 is provided with an annular shoulderor ledge 32 to accommodate the discharge terminal 3! and a washer 33.The discharge terminal is provided, in turn, with a screw threaded neck34 which carries an appropriate delivery nozzle 35 situated toeffectively and uniformly deliver the tooth paste to the bristles.

In practice, the tube of tooth paste is placed in the receptacle portionII in an obvious manner and the neck 28 is screwed into the socket 29.The ejector is placed at the right hand end of the slot 22 and the coveris closed and latched in place. Now the brush is ready for use.Obviously, by grasping the knobs or finger grips 2? the ejector ismoved, in shoe-like fashion from right to left, and in so doing, thedeflected plate 25 comes into action and serves as an expressing cam.That is to say, it rides in contact with the tube of tooth paste and bysqueezing the tube forces the paste into the delivery tube 39 andfinally expunges the paste through the nozzle Where it is taken up, bythe bristles, for use.

Changes in shape, size, materials and rearrangement of details and partsmay be resorted to in actual practice, so long as they do not departfrom the spirit of the invention or the scope of the appended claims, asis well understood.

Having described the invention, what is claimed as new is:

l. A dispensing type toothbrush of the class shown and describedcomprising an elongated hollow casing formed into a brush head at oneend and a handle at the opposite end, said casing being made up of areceiver section and a complemental cover section, said sections beingof lengths equal to each other and being hingedly connected to oneanother at corresponding ends, said head portion being provided withbristles, a paste delivery tube attached at one end to said head portionand including a discharge nozzle located in close proximity to saidbristles for delivering paste to the bristles, the intake end of saiddelivery tube being in communication with said handle portion, saidreceiver section being provided with longitudinally extendingdiametrically opposite slots, and an ejector slidably mounted in saidreceiver section and including a presser plate with one end portionslidable in the receiver section and the other end portion slidable inthe cover section, said plate being provided on opposite edge portionswith outstanding stub-shafts, said stub-shafts being slidable in saiddiametrically opposite slots and each stub-shaft having a fingergripping knob.

2. A fountain-type toothbrush of the class shown and describedcomprising a hollow elongated casing fashioned at one end into a bristle49 equipped head and having its opposite end portion fashioned to form ahandle, said casing being made up of a receiver section and acomplemental cover section, said sections being hingedly connected witheach other at the outer end of said head, detent means connected withand latching the remainin ends of the two sections together, an L-shapedpaste delivery tube having a nozzle at one end and a screw-threadedsocket at the other end, the nozzle end being anchored in the head forcoaction with said bristles and having its socket end situated toaccommodate the usual screw-threaded discharge neck of a conventionalcollapsible type toothpaste tube, said receiver section being providedwith a pair of longitudinally extending diametrically opposite guideslots, and a tube engaging paste expressing ejector unit comprising aplate having a half portion slidable in the receiver section and a halfportion slidable in the cover section and further including stub-shafts,said stubshafts extending through and outwardl beyond the said slots,and finger gripping knobs on said stub shafts.
